| Abstract: | The fluidity and filling ability of glass-forming Zr-based alloy melt in copper mould were investigated both theoretically
and experimentally. The major factors which affected the flowing behavior of the metallic melt in the mold were determined,
which provides the foundation for overcoming the contradiction between the filling and formation of amorphous alloy during
the rapid cooling process of the metallic melts. The casting factors to prepare a metallic ring were discussed and selected.
As a result, a Zr-based bulk metallic glass ring was prepared successfully.
